VALVE SPRING LIFTER.

Application filed March 31, 1925.

To all whom it may concern:

Be it known that I, ARTHUR J. WALTON, a citizen of the United States, residing at Takoma Park, in the District of Columbia. have invented certain new and useful Improvements in Valve-Spring Lifters, of which the following is a specification.

My invention is an improved tool used for the purpose of lifting the valve springs of an internal combustion engine to enable the valves to be ground without the necessity of removing the springs.

Primarily the invention has for its object to provide a very simple and inexpensive tool that can be used to lift all the valve springs of an engine at one and the same time and hold them so without the employment of screws, hooks, special cams or other more or less costly devices.

In carrying out my invention, which. has been especially designed for use on Ford engines having a single alve spring housing or chamber, I provide a Hat rigid plate with a set of slots to pass over the valve stems and under the valve spring cups or ashers and also provide the same with a pair of longer slots to fit over the valve cover screws. on which screws the tool is lulcrumed as a part of a lever, the remainder of which is constituted by a handle having a forkl-id end to straddle the edge of the plate and adapted, when the plate has been rocked, to raise the springs, to have its outer end caught under the hook rail and there by hold the plate in the lifting position while the valves are being ground.

The invention further resides in those novel details of construction. combination and arrangement of parts. all of which will he first fully described, then. be specifically pointed out in the appended claims, refer-- ence being had to the accompanying drawh1g in which Figure 1 is a perspective view of a cylinder block showing my invention in use.

Figure 2 is a detailed cross section of the same showing-the position of the parts in full lines with the springs lifted and in dotted lines before the lifting action is accomplished.

Figure 3 is perspective view of the valve spring lifter plate viewed from the underside.

Serial No. 19,673.

Figure L is a perspective view of the handle part.

In the drawing, in which like numerals in dicate like parts in all the figures, 1 is a flat narrow plate of comparatively rigid ma terial, such as steel, and this plate around one edge is provided with a series of slots 2, one for each valve spring, suitably positioned so that the plate may be inserted under all of the valve springs at one and the same time. The plate is also provided with two additional slots L to fit over the spring cover plate screws of the engine which serve as fulcrums for the plate. Associated with each slot a I preferably rovide bearing lugs or heels 5 suitably formed or secured on the plate 1. The forward end of the plate 1, where it is to be passed beneath the valve spring cups or washers, may be and prcfe'ably is, bevelled as at 3 to facilitate the entrance of the plate to position.

7 is the handle which is forked at S to straddle over the back edge 6 of the plate 1 and by means of which the plate is rocked on the hearings 5 until the springs have been compressed, at which time the lever 7 is swung laterally as on a pivot and passed under the edge of the hood holding down strip or frame part of the automobile as diagrammatically indicated in Figure 2 of the drawing, thus holding the plate in the position to hold the valve springs lifted and leaving the valve stems free from the action of the springs as long as the plate and lover remain in this position.

It will be seen that by my construction a simple and inexpensive tool has been provided for the purpose which can be readily carried in the tool box of the car, which can be n'ianufactured at a nominal cost and which will effectively serve its intended purpose.

From the foregoing description, taken in connection with the accompanying drawing. it is thought the complete construction and advantages of my invention will be clear to those skilled in the art to which it relates.

What I claim is:

1.. In valve spring lifters, a plate having a series of valve stem receiving slots along one edge, and a pair of valve-cover-screw receiving slots along the same edge, and an operating handle having provision to en.-.

gage the opposite edge of said plate for the purpose of rocking the plate on said screws substantially as shown and described.

2. In valve spring lifters a plate having a series of valve stem receiving slots along one edge, and a pair of valve-eover-screw receiving slots along the same edge, an operating handle having provision to engage the opposite edge of said plate for the purpose of rocking the plate on said screws, said handle being movable laterally parallel to the plane of the plate as on a pivot for the purposes described.

In valve spring lifters, a plate having a series of valve stem receiving slots along one edge, and a pair of VfilVE-COVGI-Si'IQW receiving slots along the same edge an operating handle having provision to engage the opposite edge of said plate For the purpose of rocking the plate on said screws, and bearing lugs on said plate associated with said valve-oover-sereu' receiving slots for the purposes specified.

4:. A valve spring lifter tool composed of two parts, a flat plate and a handle forked to receive the plate, said flat plate having a series of valve-stein-reoeivEng slots and a set of valve-eover-serew-receiving slots along one edge for the purposes specified.
